Collection and habitat data.

Most adults from New Brunswick were collected from moldy decaying corncobs and cornhusks near a mixed forest. One individual each was captured in a Lindgren funnel trap deployed in a mature hardwood forest and an old red oak forest. Adults were collected during June, August, and September.

Distribution in Canada and Alaska.

BC, AB, SK, MB, ON, QC, NB, NS ( Bousquet 1991; Majka 2010). Although Mycetophagus quadriguttatus was reported as occurring in New Brunswick by Bousquet (1991), no specimens could be located to support this record according to Majka (2010). In addition, Campbell et al. (1989) did not report it for the province, and thus, Majka considered the record as provisional. However, the above records establish this species as a member of the New Brunswick Coleoptera fauna.
